Abstract
Official abstract text for this publication.
Providing a cam clutch that has a torque limiter function adaptable to high torque with a simple structure, excellent accuracy, stability, and durability, and can be downsized and have an increased service life. The cam clutch includes: a plurality of cams disposed in a circumferential direction between at least one pair of an inner ring and an outer ring that are coaxial with each other and rotatable relative to each other; and biasing means for biasing the plurality of cams so as to come into contact with the inner ring and the outer ring. Each of the cams includes an inclination restricting portion that restricts inclination of the cam in an engaging direction by coming into contact with a locking portion that is provided in a portion of the cam clutch other than cam receiving surfaces of the inner ring and the outer ring.
First claim
Opening claim text (preview).
What is claimed is: 1 . A cam clutch having a torque limiter function, comprising: at least one pair of an inner ring and an outer ring that are coaxial with each other and rotatable relative to each other; a plurality of cams disposed in a circumferential direction between the inner ring and the outer ring; and biasing means for biasing the plurality of cams so as to come into contact with the inner ring and the outer ring, wherein each of the cams includes an inclination restricting portion that restricts inclination of the cam in an engaging direction by coming into contact with a locking portion provided in a portion of the cam clutch other than cam receiving surfaces of the inner ring and the outer ring. 2 . The cam clutch having the torque limiter function according to claim 1 , wherein the locking portion is provided in a cage member that supports and lines up the plurality of cams in the circumferential direction. 3 . The cam clutch having the torque limiter function according to claim 1 , wherein the inclination restricting portion is provided in one end portion or two end portions of the cam in an axial direction, and the locking portion is provided directly or indirectly on the outer ring or the inner ring. 4 . The cam clutch having the torque limiter function according to claim 2 , wherein the locking portion is provided in a restriction member that is fitted to the outer ring or the inner ring from a side in an axial direction.
